What is Graphite?
===================
Graphite is a free metrics collection and plotting tool for Linux/UNIX systems.
Components
=============
The Graphite suite is composed of three main components:
Carbon – this is the daemon process that listens on TCP/2003 for clients to deliver metrics to it. The metrics are stored in a Whisper database.
Diamond – client-side daemon to collect system statistics and deliver them to Carbon. Any tool written in any language can collect data and deliver it to Carbon on TCP/2003.
Graphite – the Python tool to do the actual plotting of the Whisper-stored data.
